MACHINE FOR SHAPING FLEECY MASSES.

SPECIFICATION forming part of Letters Patent No. 389,645, datedSeptember 18, 1888.

Application filed April 26, 1887.

To all whom it may concern.-

Be it known that I, EDWARD GOLDMAN, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented a new anduseful Improvement in Machines for Shaping Fleecy Masses, of which thefolforms of mechanism and combinations thereof for the purposes setforth, all as hereinafter particularly described, illustrated in thedrawin gs, and specifically pointed out in the claims.

Referring to the accompanying drawings, in which similar letters ofreference point out like parts on each figure, Figure 1 represents anend elevation ofa machine embodying my invention. Fig. 2 is a sideelevation thereof.

, Fig. 3 is a top plan view of the machine. Fig.

4; is a detail view of the mold-bed,one section of the retaining-baillying flat, the opposite section lifted atiright angles to the plane ofthe bed. Fig. 5 isasectional view on theline w w of Fig. 4, havingattached thereto one section of the bail lifted up. Fig. 6 is anenlarged longitudinal section of the blade-bearing stripper. Fig. 7 is arear view of the stripper. V

In the drawings, A is the frame of the machine, consisting, essentially,of standards a a, and side braces, a a", supporting a table, B. Theframe is further provided with an additional brace, 01*, extendingdiagonally from the four corner standards to a common center andsupplied with a socket, 23, for a purpose to be presently set forth. Thelower braces, a are provided with journal-boxes to carry a main shaft,1, upon which shaft, outside of the frame, is a master-pulley, 2,provided with Serial No. 236.264. (No model.)

belting 3 to transmit motion to the pulley 40f rod is returneddownwardly at its inner end to form a hook or bend, 9, which bend takesinto an orifice near the edge of a rod, 10, for a purpose hereinafterexplained. The rod 10 extends outwardly beyond the frame of the machineand is pivotally connected by means of a strap, 12, to the shifting-barc by a setscrew, 7. Under the bar 10 isashort orificed collar, 13, whichturns with the shaft 11.

14. is a brake-shoe the arm of which is pivotally connected within thefork of a hanger, 15, depending from brace a, and said shoe by swingingof the lever O is, through a bellcrank lever, 16, brought against theperiphery of the pulley 2 simultaneously and by the same action thatoperates the belt-shifters 0 The vertical shaft 11 is set in motion inthe following manner: Upon the driving-shaft 1, inside the frame, is asmall pulley, 17,which, through belting 18, operates a pulley, 19, uponan upper shaft, 20, journaled in the opposite braces, a, said shaftreaching across the frame away from its center. Midway of the shaft is aworm, 21, meshing into a wormwheel, 22, rigidly attached to the-verticalshaft 1l,which causes the mold-bed to turn on its eccentric axisconcurrently with said shaft 11. The several operative pulleys andgearings are arranged to have relative velocities, and I have found thatthe best results are obtained by the proportions herein set forth. Theworm-shaft 20 is caused to turn one hundred times a minute, eachrevolution operating one of the one hundred pinions of the worm-wheel22, the pitch being five-sixteenths of an inch. Gon'se quently saidwheel will turn completelyonce in a minute.

- The shaft 11 extends downward to the crossbrace a and has its bearingwithin a socket, 23. Said shaft passes upward through the table B,

through a washer, 2-1, and from thence through the eccentrically-locatedhub 25 of the moldbed 26. Above said moldbed is a collar, 27, and ascrew-plate, 28, intermediatel y embracing the forward end of themetallic guard 29 and brace-plate 30. Upon the table B are posts 31 32,to which posts the guard 29 and brace-plate 30 are rearward] y.respectively, rigidly attached by screws 33. From the points ofattachment to said posts the guard 29 and plate 30 each incline upwardlyand obliquely, and after passing over the edge of the inold-bed extendforwardly until they reach the shaft 11. Said guard and brace-plate attheir forward ends are bent over to a horizontal plane, and said heatover portions are pierced for reception of the uprising end of the shaft11, which is free to turn within the orifices of said guard andbrace-plate. The horizontal end portions of these members are rigidlyconfined between the collar 27 and screw-plate 28, as before set forth,said screw plate being orificed for passage of the uppermost end ofshaft ll. (See Fig. 3.)

Dis a stripper in the form of a hollow conical frustum, having a huh,(I. Externally and rigidly attached by screws (1 to the stripper areblunt-edged blades (1, curved in direction of their length and extendingthe full length of said stripper.

E is a short shaft which passes through the huh (I, to which it isscrewed by set-serew d, and extends from thence inside the stripper,where it is finally seated within recess (1. (See Fig. 6.) Said shaftextends in an opposite direction to and within the pulley 4.,whichpulley is in alignment with the master-pulley 2, and is connectedthereto by belting 3, as heretofore set forth. The main shaft 1, whenthe machine is operated, revolves four hundred times a minute, and therelative diameters of the master-pulley 2 and stripper-pulley t are suchas to cause the latter to make four thousand revolutions in the sameperiod of time. The shaft E passes within journal-boxes d of ordinaryconstruction, resting upon support (1, firmly bolted upon the table B.The moldbed 26 has its upper surface in an oblique plane, each sectionprovided with a recess, 34, to conform to the desired shape of onesurface of the completed fleeey mass.

To enable all skilled in analogous devices to fully understand andpractice my invention, I will describe its adaptation to manufactureshoulder-pads, for which Letters Patent aforesaid have been issued tome.

The mold-bed shown in the drawings is constructed to receive blanks fortwo pads falling, respectively,within the recesses 3t. (See Fig. 5 anddotted lines, Fig. 1.) Upon said bed is placed a blank sheet of fleecymaterialsueh as a cotton bat. Some of the thickness of this mass willnecessarily rise above the upper plane of the mo1d-bed and the greaterproportional depth will obviously appear exposed above the thinnest partof the bed. Vhen motion is imparted to the machine, the blank mass willbe trimmed off to the desired configuration.

In order to prevent the tlecey mass during manipulation from being tornfrom the bed, I provide hinged wire bails 35, adjusted to swing on theirpivots toward each side of the bed and over the blank mass, by whichmeans said mass will be held down, and, as will be readily understood,may be withdrawn by lifting up the respective bail.

By reference to Figs. 4 and 5, it will be seen that each bail has across-rod, 36, provided with a curve, 37, which holds down that part ofthe mass under said OIOSS l'Od. After the blank has been thus confined,it is now ready to have its whole surface trimmed off. As beforedescribed, the mass does not extend in uniform thickness above the bedby reason of portions thereof being sunk within the reecsses 3i. It istherefore obvious that in order to secure the desired configurativefinished surface the larger quantity of substance will be tri m med offwhere the greater depth appears above the upper oblique face-line of thebed. This is effected by means of the horizontal revolution of the bedaround its axis adjusted away from its center to impart eccentric motion to said bed, thus presenting from time to time required surfaces tothe action of the trimming-blades. Motive power having been transmittedto the machine through the driving-pulley, the stripper D is caused torevolve at a rapid velocity, in practice about four thousand revolutionsin a minute. At the same time, through revolution of the shaft ll,actuated through the worm-wheel 22,the moldbed, carrying its caged mass,is caused to turn eccentrically once in the same period of time. As themoldboard is turning, the caged mass carried thereon is caused to travelunderneath the metal guard 29, and it will be readily understood that noportions beneath said guard can be stripped off. As soon, however, asthe portions of the rotating mass are withdrawn from the guard, suchfreed portions are subjected to the action of the rapidly-revolvingblades, which blades are gaged to approach close to but not into actualcontact with the traveling mass. As before set forth,the blades of thestripper are curved in direction of their length, and the result oftheir rapid revolution is to create a powerful centrifugal suction thatstrips off filaments of the mass until its exposed surface is trimmcddown to the desired configuration. iVhen this is accomplished, the bailsare swung up on their pivots, and the blanks are withdrawn and replacedwith others for like treatment. After withdrawal, each blank is cut offby shears or dies to impart the required configuration to its perimeter.

Having now fully described my invention and the manner of itsoperation,what I claim, and desire to secure by Letters Patent, is

1. In a machine for shaping fieecy masses, mold-bed 26, having one ormore recesses upon its surface provided with swinging bails 35, wherebyto confine material within said reeesses, the moldbed beingeccentrically j on rnaled on a vertical shaft, as and for the purposeintended, substantially as described.
